Our UHN programs and services are among the most advanced in the world. We have grouped our physicians, staff, services and resources into 10 medical programs to meet the needs of our patients and help us make the most of our resources.
University Health Network is a health care and medical research organization in Toronto, Ontario, Canada. The scope of research and complexity of cases at UHN has made us a national and international source for discovery, education and patient care.
Our 10 medical programs are spread across eight hospital sites – Princess Margaret, Toronto General, Toronto Rehab’s five sites, Toronto Western – as well as our education programs through the Michener Institute of Education at UHN. Learn more about the services, programs and amenities offered at each location.

People diagnosed with aortic aneurysm might wonder what happens next. There are many possible treatment options for aortic aneurysm. If surgery is the best option for you, our multidisciplinary team of aortic experts can guide and prepare you through your surgical journey.
Please choose one of the following options to read more about surgery to treat aortic disease.
The aortic root contains the aortic valve and the coronary arteries. Your doctor may recommend surgery if an aneurysm in the aortic root is causing the aortic valve not to open and close properly.

What is valve-sparing root replacement?
What is the Ross procedure?
The aortic arch is the curved part of the aorta that carries blood to your head, neck, brain and arms. We offer the open, hybrid and endovascular repair of the aortic arch.

What is hybrid surgery?
An aortic aneurysm that involves your chest and continues down into your abdomen is called a thoraco-abdominal aortic aneurysm or TAAA.
TAAA repair is a very complex procedure. There are different ways to do the surgery (open surgery or endovascular repair) depending on the type of aneurysm.
The surgeon makes a long incision (cut) along the left side of the chest, between the ribs and down towards the belly button (umbilicus) in the lower abdomen. The weakened part of your aorta is replaced with a fabric tube called a graft.
What is Endovascular Aneurysm Repair (EVAR)?
This is a less invasive way to manage your aneurysm. A catheter is inserted into an artery in your groin and a device called a stent graft (fabric tube) is put into your aorta to seal off the aneurysm from the inside.
To repair a thoracoabdominal aortic aneurysm, or one close to the kidney arteries, a surgeon will often use a custom-made graft with branches or openings to re-attach important arteries of the abdominal aorta.
What is lumbar or spinal drain?
The lumbar or spinal drain collects cerebrospinal fluid (CSF) during and after surgery. CSF is the clear fluid that surrounds and protects your spinal cord and brain. Too much pressure in the fluid around the spinal cord can cause damage to the cord leading to paralysis of the legs and lower part of the body.
Before the surgery, a drain catheter is put into the fluid surrounding your spinal to reduce the pressure in your spinal cord and lower the risk of paralysis.
